【 Weak current College 】 cabling system and housing buildings in complexes

In formulating the security engineering, intelligent building and intelligent community comprehensive wiring system of technical programmes, unless the communication networks, computer networks and building automation systems, but also its cooperation with the housing construction. This article to comprehensive wiring and housing construction with an analysis of the relevant considerations for reader reference. In the security engineering, intelligent building or intelligence community equipped with all common facilities (such as water supply, drainage, electricity, gas, TV, monitoring, communication lines and computer network system) and the appropriate device (such as building automation control system), which are subsidiary in housing construction or infrastructure in the community, as in the building or the community of users of the service, to ensure that production activities, residence life and public services are properly. As a communications network infrastructure link — comprehensive wiring system, and housing construction, computer networks and other systems is closely, they exist in the same overall, both complementary and mutually binding continuum also has its own independent of different nature. Therefore, in the engineering design and construction must be installed and housing buildings and other facilities design and construction units combined with coordination, to take a holistic approach and solve problems in a timely manner to ensure the normal use of the purpose and requirements. In formulating the security engineering, intelligent building and intelligent community comprehensive wiring system of technical programmes, unless the communication networks, computer networks and building automation systems, but also the cooperation with the housing construction. To do this, you must fully understand and master the use of characteristics, technical features and future trends, and careful analysis study to use advanced technology, reasonable and practical programmes to achieve close cooperation, joint promotion purposes. Due to the comprehensive wiring system all cable laying and equipment installation, you need a private room (such as equipment rooms), cable shaft, concealed pipeline and grooved, reserved slots and holes, and other facilities, they are building at the design and construction, even though some internal decoration parts can become out of sync with the building construction, they all belong to the permanent building facilities. In addition, the housing construction in various public's pipeline system. As security engineering construction and intelligent building infrastructure, one of the comprehensive wiring system is dependent on the construction of structures, so in specific projects and in buildings and other pipeline facilities charge close co-ordination between, must not conflict with each other out and to avoid undue loss or legacy irreparable consequences, all these are related to the building's main features and comprehensive wiring system of communication quality. Communication lines with the introduction of housing construction parts
Intelligent buildings and external links of the communication lines are often connected with the public telecommunications network and the outside into the inside of buildings. When nature with architecture of the intelligent community, not a single building, there are also introduced in the House of communication lines, in addition to containing a public communication network connections of communication line, there are the buildings of the complex between the trunk wiring subsystem, this subsystem all complex of buildings of trunk cable or fiber-optic cable trunk, its ends are to introduce the various buildings and direct terminal connected to the complex distribution frame (CD) or building distribution frame (BD), so that the two buildings are part of the introduction of communication lines. With a public communication network connections of communication lines, complex trunk cable and complex trunk cable are comprehensive wiring system external connectivity backbone line, and its line of cable logarithmic or cable cores are many, they are guaranteed a key part of the communication barrier. Therefore, these communication lines of construction method should be used to introduce underground pipes, inside of buildings to ensure communication security reliable and easy to maintain and manage in the future. If this is the introduction of the underground piping (including underground cables or buried cables through the introduction of the steel pipe), due to the introduction of the main body of the pipeline crossing structures or load-bearing structure. To do this, the comprehensive wiring system engineering design and construction, architectural design must be with the housing and construction units in close contact with consultations resolve several problems. The introduction of the pipeline route and location
In houses and buildings of the external laying of underground pipeline route and location, city street or security engineering construction and intelligent community planning requirements of the communication lines. Underground pipe into the intelligent building of routing and location, it is for the building of housing structure and layout, equipment location, the building of the distribution frame in installation location and other pipelines have no interaction or contradictions, and other factors. The introduction of the pipeline route is linear short Czech, safe and reliable, and best nearby terminal building distribution frame and vertical cable shaft (or increase the pipeline or increased cable slot), as far as possible away from harmful to the security of communication line pipe (such as power lines, heating Groove, gas pipes, pipes etc.). As with other pipeline too near, and cannot be avoided, in order to prevent mutual influence and interference, should take effective separation or protection measures (e.g. pipelines using concrete coating, etc.); if the introduction part of underground pipeline may withstand the big pressure, to keep the communication lines are not affected by the damage, shall recommend changes in building design or select Routing technology and location may also be recommended to increase RC lintel or introduced into a pipeline of pipes with pipes, etc. Introduction of pipe hole number or reserved hole dimensions
Introduction of pipe hole number (including tube inner diameter of the hole) or reserved hole size (after the introduction of a pipe should be based on the need to take into account the basal area), in addition to meet normal use need pipe hole or holes size dimensions, should take due account of the amount earmarked for standby and future development, determination of the value and size should be consistent with the standard requirements.
In order to ensure communication security and ease of maintenance management, building and construction units, for the introduction of a pipe or reserved hole around, should make good waterproof and moisture resistant, and other technical measures, spare tube holes or reserved hole should use waterproof materials and cement mortar sealing plug, and prevent outside water or moisture from entering premises. The introduction of a pipe or reserved hole construction coordination
The introduction of a pipe or reserved holes-part construction, should be carried out at the same time the housing construction, to ensure the integrity of the construction site, to improve the quality andWork efficiency. Introduction of piping and outside of the best constructed underground pipeline. In order to facilitate the construction and future maintenance, outside of underground pipes and the introduction of a pipe connection should set one hole and hand hole, as inside and outside the boundaries of the construction section, this will not point of mutual influence the progress of the project, and can guarantee the quality of the project. Building distribution frame and parts between devices
Building distribution frame (BD) is the most comprehensive wiring system, the main hub for this in intelligent buildings will need to set up a dedicated room — equipment room (when equipped with complex distribution frame, its requirements and building distribution frame), and building complexes must take into account the following points. Building distribution frame and equipment settings and location between
Building distribution frame General Assembly in intelligent buildings between devices, it is the entire building in the Centre of cabling systems. When buildings are equipped with telephone, data (such as your computer) and other host and supporting security wiring equipment, installation of structured cabling system for building distribution frame (BD) consider between devices and the system supporting the installation of security equipment room in combination in order to save room area and reduce line length, and simple to network management and watchkeeping officers. When the integrated distribution system set up a dedicated device, the system of the host (such as user telephone switch room and computer room) need to individually set requires that each engine room off the distance between the device should not be too far away, so interrelated and reduce line length.
The design of the building should be the location of the device, try to arrange in nearby introduced into the pipeline and cable shaft (or riser slot, rose room) to reduce the building's pipe and line length to ensure that no more than comprehensive wiring system for standard in the cable, optical cable maximum distance. At the same time, also called a communication line in intelligent buildings routing and location of the arrangement is reasonable, to avoid communication lines too much after a corridor or Hall and other public places or other room, increasing construction costs, nor to installation and ongoing maintenance. The area between the equipment and technological requirements
The area between devices should be able to install all estates communication equipment (including future need to spread the device), specification size and network infrastructure, and other factors into consideration, and have certain personnel actions and activities in the area. Based on past experience of the device should not be too small area between, generally should not be less than 10m2. If you use an existing public sites (such as stairs or Hall corner, etc.), also called device actual area should not be less than the area in order to facilitate the day-to-day maintenance and overhaul testing. The device shall gas pipes, water supply and sewage pipes piping settings so as to avoid the occurrence of communication equipment. If you must travel through or settings, you should take a tight encapsulation and other protective measures, must ensure that no leakage of gas and liquids to prevent accidents affecting communication. Technological requirements between devices with various host room basically the same. Equipment room in bright light, when the maintenance and construction personnel with adequate lighting, minimum illumination shall be not less than 150LX. In order to ensure the device is in a good working environment.

The room temperature, relative humidity, fire and dust-proof and so should be basically the same as with the room. In the device should be provided with sufficient and location of appropriate AC outlet, to meet the needs of daily maintenance, these technological requirement should be timely provision of housing construction and design units for early in the design of a civil engineering and integration. If the device and the other system's host housing joint, its technological requirements should be the same. Building the backbone routing subsystem
Building the backbone routing subsystem is the security engineering construction and intelligent building cabling system of nerve centers and backbone line. Building the backbone routing subsystem includes building distribution frame, building trunk cables and building trunk cable, device and equipment. Its trunk cable and trunk cables from the intelligent building of the lower layer up vertical laying to the top-level, forming a vertical backbone cabling system. Trunk cable or trunk cable are mostly taken in the pipeline (or channel), cable shaft and the rise in housing and other facilities. The installation of laying, shall be based on the security engineering construction and intelligent building capacity number of communication lines (line on quantity and optical fiber core number), the specific conditions for buildings and other factors to select. In the design of buildings, on the decision of the embedded rising pipe (pipe elements and pipe diameter size), the channel's size, cable shaft or increase the size of the room and so on, and the general wiring system design coordination, research units. If the cabling system backbone cabling using other pipelines in the laying of the shaft, and the joint consultation of other pipeline units. On the rise in the pipeline (or channel), cable shaft and increase room request below. Increase pipeline (or channel)
Increase pipeline (or channel) installation with Ming or concealed. In housing construction design must be careful to increase pipeline (or channel) of the installation, use the pipe (the channel) of the material and the inner diameter of the variety, pipe hole (or channel internal specification size) size, there are no special requirements (such as the fire or anti-electromagnetic interference, etc.) as well as specific installation details. In order to ensure the floor surface area of a large high-rise building of communication security, facilitate horizontal cabling laying, reduce the length of communication lines and construction investment, to the appropriate location in the floor, an increase of pipeline (or channel), the formation of two rose pipeline (channel) for building trunk cable or optical fiber cable with two increases in channel, so an alternate with each other. Cable shaft
Cable shaft is sometimes simply shaft, it is the intelligent buildings important facilities. Cable shaft has a dedicated and shared in two ways. Generic cabling system for building the backbone routing subsystem of trunk cable or fiber-optic cable, generally dedicated to the power line and cable laying more favourable in the shaft, set up in this situation, simply consider cable laying position, the spacing between cables, installation fixed manner (such as channel installation or directly binding on the bridge, etc.) and fire prevention measures. If combined with the laying of cable shaft takes into account the more complex, in addition to cable safety; relates to the maintenance and management etc. Use only the cables laid in the shaft of the scenario, consider the following points .1, plus cable shaft area size is and which accommodate pipeline systemDescription, quantity, and layout (including space) and shaft in the installation of the device. More it should be noted:
· Current intelligent building weak electricity lines in a variety of communications, computers, radio, television, monitor, and fire control system, various power line in cable shaft, irrespective of the adoption of the joint or separate channel (including bridges) requires some spacing to ensure safe operation, easy installation and maintenance;

· In cable shaft in a variety of electronic circuit some to install various devices (such as connecting device). Therefore, to consider the installation location and distance between each other as well as maintenance and repair, PDS general need to set the floor distribution frame (FD), and other devices, you must have sufficient space for the installation and maintenance. In addition, we must pay attention to wiring equipment of doors should be accessible to open, in the adjacent equipment of doors open, should not interfere with each other, so as not to affect the maintenance and repair work. To this end, the combined area of the cable shaft should not be too narrow, you must have adequate installation and maintenance space. 2, in the combined cable shaft, for a variety of power line system maintenance personnel are required to enter the work, in order to guarantee the safety of equipment, and fire, moisture-proof and dust proof, cabling system for building distribution frame (FD) and other equipment should be used outside a solid sealed Cabinet, and lock the device, it uses the open type of distribution frame. In addition, various power line system maintenance personnel to share cable shaft, there should be a management system and effective measures in order to distinguish between duties and guarantee the safety of equipment. · regardless of cabling system cable is in a private or shared cable laying, installed in shaft must take practical and effective, economical and practical fire safety precautions, such as the various floors respectively in holes, installation of fire-resistive material cut off plugging or other fire closure measures around the cable and the cable itself is required for fireproof materials or fire retardant coating and smudge tight, these civil design units to be proposed, in order to take account of the design. Concrete construction details should be responsible for building and construction units, comprehensive wiring system should be combined with construction; · as intelligent building dedicated or shared cable shaft area usually less and very valuable, you must take care that the reasonable use. To this end, the comprehensive wiring system and other weak current line systems of cable laying routes and equipment installation location, should be fully taken into account, the consolidated arrangements must be reasonable layout, in order to comply with the requirements of the environment, tidy, and can adapt to future maintenance needs, not messy without layout, this will affect the day-to-day maintenance and management; · when intelligent building is very large and important nature of high-rise buildings, such as TV stations, radio stations and traffic control centre, communications hub Tower and important office building, which floor plane area larger. Therefore, usually uses the partition type of layout, or even sometimes because of building use features and services to the different needs, in addition to the object to partition (or block), its floor height and floor layers varies. In addition, this huge towering skyscraper, due to the very large internal pipeline system, the technical requirements are higher, so often in housing layout, the upper and lower the water pipe, gas pipe, etc. system located in a dedicated pipeline well. According to the electric power, light and fire control system of the line features and requirements, setting a number of different cable shaft so that their own separate laying in a dedicated cable shaft. This setting, multiple private cable shaft technology programme has the advantage that in various pipelines system daily run games and impaired or accident, the maintenance and non-interference. But its cost is relatively high, take up more floor space of buildings, building structure, because of the channel up or down through too many of the more complex, floor layout will be restricted or constraints, possible arrangement of unreasonable phenomenon. Rose room (transfer or telecom room)
In the large intelligent building standing there in the top-down form private room, the channel in order to provide comprehensive wiring system for building the backbone routing subsystem of trunk cable or fiber-optic cable laid vertically. When private room no wiring connection device (including floor distribution frame) is called the rose room. If a distribution line connecting equipment (including floor distribution frame), should be referred to as handover or telecommunications, or wiring, wiring or trunk channel. Junction is building the backbone routing subsystem and horizontal cabling subsystem connected to each of the specified junction points, it is the comprehensive wiring system in a dedicated space, is the comprehensive wiring system of the branch line main links and key parts of the body, its internal General should not have other access to the pipeline, as the comprehensive wiring system of private rooms as well, to ensure communication security reliable and maintenance management, the internal area of not less than 5m2 is appropriate, such as plane area arrangements do have difficulties may consider appropriate to reduce. Rose room settings of the specific location and the area prior to construction and design units in the design of the unified account. As intelligent building floor plan layout was tensions or cause difficulties in the area and other factors could not suffice, the increased room available on stairs, corridors or Hall and public areas are more subtle, designating certain area to set up, but require increased room locations on each floor are consistent, its area is basically the same (allowing the highest skyscraper in several floors of the rose room can slightly less) so up and down through the communication lines can be directly routed and fixed installations, both save communication line project investment, but also convenient for daily maintenance. Rose room should have a separate portal, in order to guarantee safety and ease of Administration should be locked. In addition, according to the fire engineering related construction standards, upper and lower floors through holes and cable crossing, etc should provide effective fire prevention measures. Floor level routing subsystem
Comprehensive wiring system of horizontal cabling subsystem is distributed to all intelligent buildings in various parts of the floor, covers almost all floors in the building of the whole area, is the most comprehensive wiring system is cumbersome and complex, but very important part of the extension is the intelligent building engineering design and construction requirements and communication professional synergies and mutual coordination and research to solve some of the contradictions and up. It usually involves floor horizontal cabling subsystem cable laying the pipe or channel routing, location, size and specifications, communication terminations location and quantity reserved cable wear-and-drop routed hole size and specificLocation, as well as a variety of issues such as strengthening the installation. Requirements to meet current user needs, but also for future development has sufficient leeway. In particular, the buildings have been built, its floor horizontal cabling subsystem the required pipe or channel, generally use the downlead mode, you must consider certain compatibility and flexibility to adapt to future changes in the level of wiring subsystem. Reserved to install communication terminations holes size should be based on the selected part models and specifications, must be in line with each other to facilitate installation. In the security engineering construction and intelligent buildings such as the internal decoration standards higher places, especially important public areas (such as meeting rooms and Conference halls, etc.), its extremely ornate decoration. Therefore, the construction of comprehensive wiring system engineering and installation method, you must obey the principal and the entire situation, and building interior decoration project coordination, so that in the construction process interaction and interference.
